When using or purchasing grinding wheels, you often see the mesh size of the grinding wheel. So, which numerical parameter does this mesh size represent? Today, Mingsha Grinding Tools will explain to you.
The mesh size of the grinding wheel refers to the size of the abrasive grain size, which is divided into abrasive particles and fine particles according to their size. Particles with a particle size greater than 40 μ m are called abrasive particles, while those smaller than 40 μ m are called fine particles. A 60 mesh abrasive particle indicates that its size can pass through a sieve with 60 holes per inch length, while a 600 mesh abrasive particle indicates that its size can pass through a sieve with 600 holes per inch length.
The mesh size of the grinding wheel is mainly related to the surface roughness of the workpiece during grinding. When performing rough grinding, the grinding allowance is large and the required surface roughness value is also large. Therefore, smaller mesh grinding wheels should be used to prevent clogging and heating of the grinding wheel. When performing precision grinding, if the roughness value of the workpiece surface is low, a grinding wheel with a larger mesh size should be selected. The finer the abrasive particles, the better the roughness of the workpiece surface.
